While the rail industry has existed since the 1800s, the introduction of modern technology has changed how railways operate and maintain their systems. This technology shift, combined with a declining skilled workforce in traditional industries such as rail, has resulted in a significant challenge for many transit operators and railways around the globe to maintain both safety and achieve the operational improvements, cost efficiencies, and social/environmental goals demanded by their respective stakeholders.

With one of the largest teams of rail systems experts in the world, we can leverage the latest technologies and methods to deliver safe and reliable systems meeting even your most rigorous standards.



One of the fastest changing technology sectors in transit, communications systems require constant upgrading and monitoring. From fiber-optic backbones to the operations control center, your communications systems need to be reliable and robust. Our extensive team of communications experts have worked with all the suppliers of communications equipment, and they know all their strength and weaknesses. They keep on top of new technologies and can help you specify technologies that won’t be out of date before they are installed.

Signaling and Train Control

The heart of your safety program relies on your signals and train control systems like PTC and CBTC. They must be right every minute of every day you run service. For buses and light rail, signal pre-emption also must be flawless to meet schedules and keep passengers, operators, and motorists safe.

Traction Power

Managing the electrical power needed to move a train along a railway track involves multiple components. Our rail system’s capabilities are among the best, most robust, and innovative in the industry.
